Frankie Dettori will appear before a BHA disciplinary panel on Thursday to try to reduce what could be an incredibly costly spell on the sidelines.
The jockey, who is in his retirement year, faces missing a total of 17 days' racing if he has to serve two bans issued for breaches of the rules last week at Royal Ascot.
He was suspended for nine days (July 4-12) after being found guilty of careless riding on the King and Queen’s horse Saga in the Wolferton Stakes, as a result of which he is set to miss the ride on Emily Upjohn in the Coral-Eclipse Stakes.
Then on Tuesday the BHA’s Whip Review Committee imposed an eight day ban after Dettori was found to have used his whip seven times on the Queen Anne Stakes runner-up Inspiral.
The ban was double the usual penalty for exceeding the strike limit by one, of four days, because it occurred in a Group 1 race.
The second suspension has ruled him out from July 13-15 and 17-21, which covers the July Cup, the only British Group 1 race Dettori has not won.
He has appealed against the careless riding ban which will be heard by the independent panel via Zoom on Thursday.
Dettori was one of a number of high profile jockeys sentenced by the Whip Review Committee for Royal Ascot offences.
Oisin Murphy, who also went over the permitted level by one on King George V Stakes runner-up Valiant King was given an eight day ban (July 11-15 and 17-19).
James McDonald received a 14 day ban and fined £400 after going two over the whip limit on Artorius in the Queen Elizabeth II Jubilee Stakes.
Daniel Muscutt is another missing Newmarket after he used his whip seven times when riding Canberra Legend into fifth place in the Hampton Court Stakes.
